To (in/l [Ii/wilt 1'! In/my calmer/e:

Be it known that we, LUTHER .l'. ZUnnNnR and AUeUs'r F. BAIIIRA, J12, citizens of the United States, residing at Newcastle, in the county of Lawrence and State 01" Pennsylvania, have invented certain new and useful l ne proveincnts in Invalid-Beds, of which the following is a specification.

Our inventioi'i relates to beds for invalids, and has for its object the provision of a bed in which the invalid may bemoved from one side to the other when it is desired to change the bcdclothing without seriously disturbing theinvalid.

The construction and advantages of our invention will more fully appear hereinafter and by reference to the accom pan ying drawings, in which- Figure l is an end view of our invention in a flat position; Fig. 2, a view showing it in position to change the position of the invalid; 3, a view showing the position assumed immediately after the invalids position has been changed; Fig. 4, a fragmental top plan view; Fig. 5, a detail view of the rod fol-supporting the device in the bedstead; Fig. 6, a detail view of one of the supportingarms; Fig. 7, an end view of the mattress; and Fig. 8, a View partly in section, showing one end of the bedstead, one of the supporting-bars, and a fragment of the mattress-support, showing their relative positions.

l n the drawings similar reference characters indicate correspoinling parts throughout the several views.

A represents one of the ends of a bedstead of the type in general use in hospitals, sanatoriums, &c.-viz., of the metal type and having a cross-bar a.

i; represents one of the su pporting-bars for the bed, made, preferably, of angle-iron to insure stability and supported by angular braekets 7), that rest on cross-bar a, it being understood that there is a supporting-bar B provided at each end of the bedstead.

C "U represent supports secured to bar B and having journal-bearings c in their upper end. As shown in the drawings, one of said supports C is placed substantially in the center of bar 13, while the other support is placed between the lirst-named support and the end of said bar B.

The mattress-s11 pport consists ol three parts D, E, and F, the part D being the largest part and consists of a side bar (Z and two end bars (5. The free end of bars (55 are connected by a bar G, that is curved downwardly at each end, as shown at 7.

ll represents bars connecting bar (1 with side bar a, each olsaid bars ll beingbentdownwardly at the end adjacent to bar 1/, as shown at /i.

The part E (the middle section, of the mattress-sup 'iort) has end bars (2, connected by another bar G, and the part F (the other outer section of the mattresssupport) has aside bar 2, end barsf", a bar Gr, connecting the ends of bars f, and bars H, connecting the side bar f and the last-mentioned bar Gr.

1 represents springs attached to bars (3i and H, and J straps connecting the tops of springs .I

K represents the mattress, which, as shown, is made in three parts connected by a web or lacing]: on their upper abutting edges, the three parts of the mattress being the same width as the three parts I), E, and F.

L remesents arms secured to the inner ends of bars (1 and f and having holes I, while M re n'esents a plate secured to each bar having slots m and projections N, with holes a to register with the holes O representsangular levers having pins 0, that are inserted through holes and a and rest in bearings c. The ends of lovers 0 epposite plates M are slotted, as-shown at o, and P represents bolts mounted in said slots m and 0, having wing or thumb nu ts thereon.

Q, represents projections on arms L to act as stops for the free ends of levers O in operating the bed.

The operation of our invention is as follows: The patient is lying on the part I). The parts E and F are then raised up and over the patient, as shown in Fig. 2. The part 1) is then raised, the other parts E and F being thus forced back to their original position by means of the projections Q contacting with the free ends of levers 0, and the patient is deposited on the parts E and F. The part D may then be returned to its original position and a change of bedclothes made, after which the patient may be returned to the part D by raising said part as far as it can be raised or until the projections Q on the arms on said part D come in contact with the ends of levers O journaled therein. Part F is then raised and the patient returned to his originalposition on part D by swinging said part D back to its normal position. The parts E and F are then returned to their original position.

It Will be understood that levers 0 should be so arranged, by means of bolts P and slots m, as to suit the condition and convenience of the patient, it being apparent that the nearer the top of slots at the lev'ers are secured the less swing can be given the parts E and F, and vice versa. It will also be understood that the mattress-sections must be secured to the corresponding sections of the bed.

Having thus described our invention, what we claim is 1. In an invalid-bed, three separable sections, a slotted plate secured to each end of the middle section, an arm secured to each end of the other sections, means to pivotally connect said plates and arms, and stops to intercept said arms adjustably mounted in the slots in said plate, substantially as shown and described.

2. 1n an invalid-bed, three separable sections, a slotted plate secured to each end of the middle section, an arm secured to each end of the other sections, means to pivotally connect said plates and arms, and means to limit the movement of the adjacent sections relative to one another, said limiting means being adjustably secured in the slots in said plate, substantially as shown and described.

3. In an invalid-bed, three separable sections, the middle section having a slotted plate secured at each end, the other sections having arms secured thereto, said plates and arms being perforated in aliuement, angular levers having pins to ride in the holes in the plates and arms and provided with means to adjustably secure them in the slots in the plates, and means to support said pivoted sections, sub stantially as shown and described.

at. In an invalid-bed, three separable sections, the middle section having a plate secured at each end with curved slots therein, the other sections having arms secured thereto, said plates and arms being perforated in alinement, angular levers having lateral pins to ride in the holes in the plates and arms, a bolt secured to each lever and inserted in the adjacent slot in the plate, a rod at each end of the bed, and journal-bearings secured to said rods to receive the projecting ends of the pins, substantially as shown and described.

5. in an invalid-bed, three separable sections, the middle section having a plate secured at each end with curved slots therein, the other sections having arms secu red thereto, said plates and arms being perforated in alinement, angular levers having lateral pins to ride in the holes in the plates and arms, a bolt secured to each lever and inserted in the adjacent slot in the plate, means to support said pivoted sections, and a mattress formed with three separable sections but joined along their abutting top edges secured to said pivoted sections, substantially as shown and described.

6. In an invalid-bed, three separable sections, rods secured to said sections and depressed below the level thereof, springs secured to said rods, the middle section having a plate secured at each end with curved slots therein, the other sections having arms secured thereto, said plates and arms being perforated in alinement, angular levers having lateral pins to ride in the holes in the plates and arms, a bolt secured to each lever and inserted in the adjacent slot in the plate, means to support said pivoted sections, and amattress formed with three separable sections but joined along their abutting top edges secured to said pivoted sections, substantially as shown and described.

7. In an invalid-bed, three separable sections arranged longitudinally of the bed, a plate secured to each end of the middle section, said plate having curved slots therein, the outer sections having arms secured at each end, said plates and arms overlapping and perforated in alinement, angular levers having lateral pins to ride in the holes in the plates and arms, a bolt secured to each lever and inserted in the adjacent slot in the plate, a rod supported at each end of the bedstead, and journal-bearings secured to said rods to receive the projecting ends of said lateral pins to support the sections above mentioned, substantially as shown and described.

In testimony whereof we hereto our signatures in the presence of two Witnesses.
